IBM PC-DOS 7.1 Rev0, Floppy image 1440kb

Dosember Edition

This is the "True Final Version" (TFV) of IBM PC-DOS 7.1

TWO (2) IMPORTANT INCLUDES:

1: Patched SYS.COM, without it sys commands, ie "a:sys:", will report "incorrect DOS version", with it sys commands will work correctly as PC-DOS 7.1 Rev 0 BLD134. Please replace sys.com in image with one in patched folder.

2: PCDOS2000_files_for_PCDOS71.zip = PC-DOS 2000 Files to COPY to your install. This will complete OS install. DO NOT OVERWRITE EXISTING FILES!

WHY #2:

NOTE:

The files from the SGTK package (the PC-DOS 7.1 Rev 0 BLD134 image in this archive) do not represent a complete OS installation; a number of DOS commands and utilities are missing. You can complete your installation by supplementing it with files from PC-DOS 2000 (Supplied in included PCDOS2000_files_for_PCDOS71.zip).

Built from:

- IBM PC-DOS 2000 (freeware, in free release of Connectix VirtualPC 4.0) & IBM Server Guide Toolkit v1.037 (also freeware)

- Inclusive of ALL BID Levels to B134 / v1.34 dated: 2004.02.27

To use/install:

- Use standalone from floppy/USB

- Or Copy Contents of floppy o bootable hard disk partition

Notes:

- You may need to edit CONFIG.SYS & AUTOEXEC. BAT to your needs/liking.

- You may need to patch SETVER.EXE to look for version 7.10 instead

- You may need to disable EMM386.EXE for FSHARE.EXE to work

To Build Yourself:

The following, simplified procedure supercedes my OP. It no longer requires a PC-DOS 2000 boot disk as an intermediate step.

I. Build the installation disk

Download a copy of the IBM ServerGuide Scripting Toolkit, DOS Edition (SGTK): https://www-947.ibm.com/support/entry/p ... MIGR-53564 and unpack it.
Locate the PC-DOS 7.1 files in sgdeploy/sgtk/DOS/ and the bootable disk image at sgdeploy/sgtk/ads/images/tk_raid.vfd.
Using a disk image editor (Winimage (http://www.winimage.com/download.htm is excellent)), open tk_raid.vfd.
Delete everything except IBMBIO.COM and IBMDOS.COM.
Copy all the 7.1 files from sgdeploy/sgtk/DOS/ to the root of the image, except for IBMBIO.COM and IBMDOS.COM.

IF NOT USING VM > SAVE .IMA > WRITE TO FLOPPY > DONE

II. Create a DOS VM

Create a basic DOS VM in VirtualBox. If you give it a name with DOS in the title, VB will automatically select DOS. Otherwise select Type: Other and Version: DOS. Just take all the default settings.

III. Install PC-DOS 7.1

Boot your DOS VM from the installation image you created in Step I.
When you get to the A:\> prompt, run FDISK32 1 /pri:500. Ignore the error message.
With the boot image still mounted in A:, reboot the VM.

Back at the A:\> prompt, run the following commands in order:

A:\>FORMAT C: /V:PCDOS71 /S /U
A:\>MKDIR C:\DOS
A:\>XCOPY *.* C:\DOS /S
A:\>COPY CFGFILES\*.* C:\

IV. Done!

Unmount the floppy image from the A: drive and reboot the VM. You should get a C:\> prompt. Type VER to check:
